Yes, I was happy to get all the iOS Celestion IR packs. They are a massive upgrade and economical on the iPad at least. The speakers were chosen carefully and I have not felt limited by the palette of sounds that’s seem far more efficient and more realistic. They even seem louder and more direct, which is good because I have a Celestion V30 in the cheap Traynor tube combo that is the amp for my ipad. It was muddy at times with the prior packs.

I'm using the IRs, simply because Bias's GUI doesn't allow direct entry or parameter view, so its really, really really hard for me to make sure I am setting the mics and stuff the same.

I would sooooooooooooo much rather have that (and savable as presets!) so that I don't have to make 12 different versions of every head, send them to the cloud, get them from the cloud, then load them in bias fx then send those to the cloud and load them from the cloud....just the thought of all this file management makes my head hurt
